Answer:
it's the fourth one
Step-by-step explanation:
Solve all the problems using exponent rules and the last one equals 632
Using it's concept, the probability that you flip heads and roll a number greater than 5 is:
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, we have that:
- The probability of a head is 1/2.
- The probability of a number greater than 5 is 1/6.
Hence the probability of both events is:

<span>.75(x+3)=.5(3)+x
</span><span> You already have 3 liters, and you are going to add x liters.
50% (.5) of the 3 liters is acid, and 100% (1) of the added x liters is acid. You will end up with (3+x) liters.
If you have been assigned this problem, you should be able to solve this equation...

Answer:k = </span>

<span>
Explanation:To get the value of k, we will need to isolate it on one side of the equation.
This can be done as follows:
d = a(2+kt)
<u><em>1- get rid of the brackets using distributive property:</em></u>
d = a(2+kt)
d = 2a + akt
<u><em>2- Subtract 2a from both sides of the equation:</em></u>
d - 2a = 2a + akt - 2a
d - 2a = akt
<u><em>3- Divide both sides of the equation by "at":</em></u>
